It looks like "gsl_interp_cspline" is a global variable, not a type, so you probably want to be doing something like: (defcvar "gsl_interp_cspline" :pointer) That should define a symbol macro *GSL-INTERP-CSPLINE* that will get the value of that C variable as a foreign pointer (I must admit, it seems a little weird to me to name the symbol macro with the special variable naming convention, since it's not actually special...)
